Hey Nick,
I actually just tried out a 5030 the other day, after coming from a 9950. There is a big difference between the two, I think. The 5030 is a foam injected stick that has a very thin profile and a smooth, rounded handle (that is, it feels like the corners on the handle have been sanded or shaved to have a more "rounded" feel). Also the paddle feels more laminated and smooth (think old Koho Revolution) as opposed to the more "raw" fiberglass feel of the 9950. The 5030 reminds me alot of Hespeler RTXGs - but are a TON more durable. I honestly thought the 5030 would be break fairly easily, especially on the edges of the paddle, which are not laminated, but it has stood up well against Junior A-level shooters.
The thinner profile also improves puck feel, I think. The curve is a little much for me (it's a Thibault pattern) but it has a good deal of flex to it and was good at getting the puck up and out.
Even with all this, I'm pretty sure I'll be going back to the 9950. The 5030 is not a bad stick, but I'm just not all that comfortable with it. I guess I just like a "beefier" feeling stick (ha ha!
).
I'm pretty sure there are some other threads here that don't have such glowing praise for the 5030. You might want to check them out too. Just search "5030" and you should get some hits.
Good Luck!
